This is actually a build I just started also, the stats are pretty good I'd probably stop around 40 int and maybe throw 2 more points in str but that's up to you just my opinion. I really don't think the lower endurance will hurt to much due to most dex weapons being light just depends on what armor you plan on running with.
45 INT for best point/mag adj with logan's catalys is a must if not 50. 40 DEX is enough.More than that is a waste imo for dex/int. 19ATT to be able to spice some pyro too on that spell list. 40VIT And fine tune END depending on your equips and if you want 120 or 125 or even less than that total SL. Other than that thats basicaly the best dex/int for me.
I find it kind of funny,I find it kind of sad, The dreams in which I'm dying , are the best I've ever had!
